摘要： A disk player having a self-compensating dynamic balancer so as to subdue internal vibrations due to an eccentric center of mass of a disk, a self-compensating-dynamic-balancer integrated turntable, a self-compensating-dynamic-balancer integrated clamper, and a self-compensating-dynamic-balancer integrated spindle motor which are employed in the disk player. The self-compensating dynamic balancer is embodied by forming a cavity in a turntable, clamper, a rotor of a spindle motor, or the like, and disposing movable members including movable rigid bodies and/or a liquid therein. Internal vibrations due to the eccentric mass of the disk are subdued effectively the movable members moving away from a revolution center according to respective centrifugal forces where the self-compensating dynamic balancer rotates.

摘要： A disc device in which, when a driving unit including a self-chucking-type rotatable table is moving towards the front, a disc is transported by a transporting roller, and is sent between the rotatable table and a guiding plate. At this position, a driving unit moves upward, causing the disc to be sandwiched between the rotatable table and the guiding plate, so that the disc is clamped to the rotatable table. Thereafter, the driving unit moves downward, and moves further towards the back side of a housing in order for the disc to be drawn into the housing. A disc device using a self-chucking-type rotatable table requires a complicated mechanism for pushing a disc against the rotatable table, so that it is difficult to reduce the size of the disc device.
摘要翻译：一种盘装置，其中当包括自吸夹式旋转台的驱动单元朝向前方移动时，盘由输送辊输送，并被送到可旋转台与引导板之间。在该位置，驱动单元向上移动，使得盘被夹在可旋转工作台和引导板之间，使得盘被夹紧到可旋转工作台上。此后，驱动单元向下移动，并且进一步朝着壳体的后侧移动，以便将盘拉入壳体。使用自吸式旋转台的盘装置需要用于将盘推到可旋转台上的复杂机构，因此难以减小盘装置的尺寸。

摘要： In a spindle device mounted to a disc driving apparatus, a mist seal which blocks a mist of lubricating fluid, an oil seal which prevents the lubricating fluid from flowing out, and an oil pool which prevents surplus fluid from flowing out, are combined and disposed so that the lubricating fluid from a dynamic-pressure-fluid bearing is prevented from flowing out or splashing into a clean space. As a result, inconveniences such as a head crush or a head absorption can be avoided, and a reliable spindle device is realized.

摘要： In the disk clamping mechanism of the present invention, a turntable has a columnar section capable of fitting a disk-shaped medium and a circular supporting section capable of supporting the disk-shaped medium. A clamper has a circular pressing section and is magnetically drawn toward the turntable so as to hold the disk-shaped medium. A circular hole is formed in the columnar section of the turntable. A positioning boss is provided in the bottom face of the clamper and inserted into the circular hole. An outer circumferential face of the positioning boss is formed into a tapered face. The tapered face contacts an inner edge of the circular hole when the clamper is held on the turntable on which no disk-shaped medium is mounted. The insertion of the positioning boss into the circular hole is stopped when a distance between the pressing section of the clamper and a supporting section of the turntable is shorter than thickness of the disk-shaped medium.

摘要： A data storage device has a disk-drive motor, a head-drive motor, read/write heads, and an integrated circuit board, all mounted on a single-piece integral frame and enclosed by a casing. Each motor is mounted within a surface recess on the frame via an attachment lip integrally formed into each recess. Additionally, a bend is formed across the width of the frame. The single-piece frame, frame bend, and surface recesses provide the data storage device with significant structural rigidity and thus enhance the ability of the device to withstand the application of externally-applied forces.

摘要： A disk player according to the present invention comprises a magazine and a player portion. When a disk is played, the magazine is loaded in the player portion. A plurality of plates on which disks are to be put are stacked in the magazine. Each of the plates can be separated from each other by not sliding but moving upward and downward. In this separated state, a pickup arm which is equipped with a pickup and a chucking mechanism enters a portion between the plates. After the entrance, the plates in steps above the selected disk further rise, and the plate on which the selected disk falls. By the fall, the selected disk is put on a disk table in the chucking mechanism. Thereafter, a claw member protrudes from the disk table, to clamp the selected disk through a center hole of the selected disk. The necessity of a member for rotatably pressing the selected disk from above is eliminated. Consequently, the disk player can be made thin.

摘要： The rotational balance by weight of a rotational driving apparatus for a disk is adjusted in a state in which a hub or a dummy member equivalent to the hub is fixed onto a turntable while a motor thereof is driven. When the hub is mounted on the turntable, rotation with excellent weight balance can be achieved, resulting in prevention of vibration due to imbalance of weight.
